Title: Controlling of electron beam quantity
Inventor: ISHIOKA HISAMICHI
IPC: H01J37/305
Filed: 1988-03-14
Abstract: PURPOSE:To easily follow the change when the electron beam quantity set for an object to be radiated is changed by calculating the quantity of the electron beam permeating a metal foil and changing the electric power fed into a vacuum container from a high-frequency power source. CONSTITUTION:When the electric power is fed into a vacuum container from a high-frequency power source 11 to generate plasma, it collides with a cathode to generate secondary electrons. The cathode current Ic is the sum of the ion current and the secondary electron current, this current Ic is inputted to an arithmetic unit 15. Emitted secondary electrons permeate a metal foil hermetically closing the opening section of the vacuum container, the quantity of the electron beam permeating the metal foil when the electron beam is radiated to an object to be radiated arranged on the outside of the metal foil is calculated based on the current value flowing into the cathode from a high-voltage power source applying the more negative potential than the container to the cathode, the electric power fed into the vacuum container from the high-frequency power source is changed until this calculated value becomes equal to the electron beam quantity set for the radiated object. When the electron beam quantity set for the radiated object is changed, the change can be easily followed.

Title: Image forming device
Inventor: SAITO YOSHIHIRO
IPC: G03G15/16
Filed: 1988-03-16
Abstract: PURPOSE:To prevent image quality from deteriorating caused by pollution of a guide plate by providing an electrostatic charger which is same polarity as the electrostatic charge polarity of the toner of a toner image to be transferred on the guide plate which carries transferring materials. CONSTITUTION:The electrostatic charger 5 whereby guide plates 6a and 6b are kept at fixed potential of a prescribed polarity by a power source 5a in accordance wit the polarity of the toner which is currently used is disposed near a carrying route 6. In addition, by a developing device 2, a positively electrified toner which adheres to the dark part of an original image is electrostatically charged to be fixed potential in the same polarity by a post electrostatic charger 4. At this time, non-image part being a base part holds an electric charge and potential rises. Since the guide plates 6a and 6b are electrostatically charged in the same polarity as the toner, the toner on the surface of a photosensitive body does not adhere to the guide plates. Thus, the toner which adheres to the guide materials is not attracted and image quality of print image is prevented from deteriorating.

IPC: B23K26/18
Filed: 1992-02-17
Abstract: PURPOSE:To suppress the thermal influence generated in a material to be processed at the time of processing the work piece by using a pulse laser beam. CONSTITUTION:The prescribed parts of both surfaces of the material 5 to be processed are coated with protective layers 10 and the protective layers 10 are irradiated with the pulse laser beam 2, by which the processing to penetrate the protective layers 10 and the material 5 to be processed is executed or the processing to remove the surface layer is executed, thereafter, the protective layers 10 are removed from the material 5 to be processed. Since the prescribed parts of both surfaces of the material 5 to be processed are coated with the protective layers 10, deposited layers are not directly formed on the surfaces of the material 5 to be processed and the material 5 to be processed is not directly irradiated with the part near the peripheral edge of the pulse laser beam 2 where the density of the energy irradiation is low and which is not suitable for processing and, therefore, the deterioration in material quality hardly arises around the hole formed in the material 5 to be processed.
